Excellent!  ZPT seems to be shaping up rapidly.  I must confess I'm a
little disappointed by the absence of cond().  Did it get discarded
somewhere along the way or just not make it in yet?  I'd really like
to be able to do something like:

<p tal:content="python:cond(foo(), 'Replacement text', default)" >
   Some default text
</p>
